and in Great `Britain August 11, 1931 9 Claims. v(C1. io- 131) This invention relates to electric lamps of the reflector type and `has for its `object to provide an improved construction of electric incandescent lampof the reflector type'Which is particularly adapted for use Aas an electric advertising lamp. The electric Vincandescent lamp hereinafter described and claimed is preferably of the type having a parabolic orother reector. It haslheretoforebeen proposed to provide a fixed or portable luminous advertising device in which the text, letter presser designs constituting the advertisement is arranged circularly and in reverseorder around and directly onan electric incandescent bulb and concentric with the axis thereof o1' on to the peripheral surface of an opaline white or coloured sleeve orthe like fitting round the base of the bulb where it is in contact with a parabolic elliptic or semi-spherical reflector of copper, brass polished White metal or silver glass of any dimensions suitable fordisplaying the vdesired advertisement. Insuch advertising device as aforesaid it has been proposed to form the text or drawings bycut out patterns of paper celluloid or other glued or secured to the'l'ampl or sleeve.

Accordingio the present inventionan electric incandescent lamp is provided wherein readable and/or pictorial advertising or other matteris mounted on permanent or removable and replace-- able and/or interchangeable means surrounding the lamp bulb the letters or other elements forming `the said advertisingmatter being so aligned that said matter is disposedrparallel to the axis of 4the reflector and when rendered visibleby reflection appears radially on the rellector when the lamp is lit with or without a coloured -or multi-coloured appearance imparted to the reflecreflector may be produced over the Whole or a part of the surface thereof and may appear radially reflected therefrom or radially and circularly reflected therefrom the latter appearance being obtained'for example by circular alignment of the letters on successive parts ofthelmeans aforesaid and the colour effects may have the appearance of radially or radially and circumferentially arranged zones, segments, cir-sectors, or any desired combination thereof. It should be clearlyunderstood however that any rdesired colour, multicoloured, marled, mottled, satinized, frosted or other appearance or any desired' combination of such appearances maybe imparted to the lamp n reflector by the means in accordance With the Gill present invention. i i

In order that the invention may be clearly understood and readily carried into effect reference is made to the accompanying drawings-which showdiagrammatically and by `vvayof example constructions of incandescent electric reflector lamps in accordance With'the present invention.'

Referring to Figures 1, 2, 3, and 4 of the accompanying drawings an incandescent electric lamp is as heretofore provided with a reflector 1 and a front glass 2 hereinafter referred to as the lamp glass. 3 is a tubular bulb or it may be a 4 are the electric leads to the filament in the bulb 3. It is preferred but not essential that the reflector 1 be of the parabolic type but the said reiiector may be of any other suitable type and is provided on its inne).` surface 5 with a highly polished surface. In the interior of the lamp is an inwardly projecting,hollowmember of a wholly or partly transparent and/or translucent or partly opaque nature. The tubular member 6 forms a sleeve and is provided with a rearward extension 6 Vof a larger diameter than the sleeve 6 and also an external screw thread 7 which is engageable by a closing cap 8. The cap 8 is provided with a circular annular flangeQ adapted to be retained in position on the rear of the reflector by screws 10 ,rigidly secured tothe reilector casing 1 and nuts 11. The forward end of the sleeve is closed as at 12 and shouldered `and on the sleeve are mounted a plurality of glass panels or strips 13 these glass panelsV or strips being coloured or multi-coloured and held in position on the sleeve 6 by helical circular springs 14 and 15. Y'Ihe reflector casing is pivotally mounted as at16 on a standard 17 having a base plate 18. The tubular member 6 may however as shown in Figure 3 be loosely supported between-the lamp glass 2 and the inner surface 5 of the reflector 1. It may however as hereinafter described be formed integral with the lamp glass 2 as shown in FigureV 14 or it may be supported by suitable rings or clips by the reflector itself as shown in Figures 15 and 16 hereinafter described. VAs shown in Figure 5 the tubular member 6 may be hollow and cylindrical or of hollow oval form as shown in Figure 6. As shown in Figures '7 and 3 the tubular member 6 is of hollow polygonal formsuch as hexagonal and is made in one piece, The tubular member 6 of whatever form bears readable or pictorial or other desired advertising matter with or without a coloured or multicolouredappearance. In Figures 9 and 10 the hollow tubular member 6 is built up of a plurality of strips 18, 19, 20, 21, 22 and 23 of transparent translucent, marled, mottled, frosted, satinized and/ or coloured, multi-coloured or partly opaque material or any desired combination thereof. It

f should be clearly understood howeverthat there may be any suitable number of strips of transparent or partly opaque materialother than that shown in FigureV 9 and that the cross sectional form of the tubular member 6 may be a combina# tion of any of the aforesaid cross sectional forms. These strips 18, 19, 20, 21, 22 and23 may be secured or held in position by adhesive or they may be loosely mounted on the tubular member 6 and held in place by wire clips 24 having projecting tongues 25 as shown in Figures 9, l0 ,and

11 the said clips being disposed one at each end of the strips and surrounding the said strips and of a similar shape thereto. In Figures 12 and 13 the tubular member 6 is shown as being formed as an inner tube 26 of transparent material such as glass on which are superimposed eight strips 2'?,V v2.8, 29, 30, 31, 32, 33 and 34 of transparentY or partly opaque material. The inner or outer surface of the tube 26 or strips may bemottled, marled, satinized or frosted and uncoloured or coloured or multi-coloured by the application of transparent coloured material or coloured medium thereto or the colouring medium may b e incorporated in the strips. One or more than one'str'ip may however be formed of coloured glass or a sheet of coloured glass may be superimposed and suitably secured to a sheet of plain glass to obtain the desired colour eifect.

The tubular member 6 in all of the aforesaid constructions is provided on its outer surface with advertising ,orV other readable or pictorial matter such for example as the words attractive, feective as shown in Figures 1, 3 and 4, Figures and 4 showing theappearance of the words on the reflector when the lamp is lit.` The remaining part of the tubular member l6 may, as shown in Figure 4 beso formed as to produce apparently frosted surfaces 35, 36l and coloured surfaces 37, 38, 39 and 40 on the reflector, any desired colour being obtained by the superimposition on the Vtubular member 6 of interchangeable and/or replaceable strips of frosted transparent material and/or transparent coloured or multi-coloured material. Instead of obtaining the coloured or coloured and frosted appearance indicated in Figure `4 by the use of transparent strips applied tothe external orinternal surface of the tubular member 6 the latter may,whatever its form, be coated with a trans-A parent, frostedand/or colouring medium to give the same effect or the said tubular member 6 may have lthe colouring matter or material or medium incorporated therein during the coursel of manufacture.v v

In Figures '7 and 8 the sides of the hexagonal tubular member there shown may be marled, mottled, frosted, satinized and/or coloured ormulti-coloured by coating, spraying or bythe frosted, satinized coloured or multi-coloured transparent Vmaterial secured thereto as by ad-, hesive.l A suitable lmaterial for such purpose is celluloid both in` its inflammable and non-im flammable form orl any other transparent Vma-` terial of a like nature. In the construction of tubular member 6 shown in Figures 9 and 10 the strips 18, 19, 20l etc. are removable, replaceable and interchangeable and anyone or more than one of these strips is provided with advertising matter on its inner or outer surface. Suchadvertising matter is of a readable, pictorial or combined readable and pictorial or other desired form. shown inv Figures `12 and 13 the strips 27,Y 23, 29, 30, 3l, 32, 33 and' 34 when loosely supportedon the tube 26 are removable, replaceable, renewable and interchangeable and any one or more than one strip of such strips bears advertising matter of any suitable or desired nature on its inner or outer surface. Further where strips are used they may be so arranged as to slide on and into position on the tube 26 which may be formed with guide ridges. In Figure 14 the `tubular member 6 which is of a blue or other colour and/or marled mottled or frosted throughout its length or only In `the construction of tubular memberapplication thereto of strips of marled, mottled, v

for a part thereof'is shown as'being formedin one with the lamp glass 2but it should-be :clearly understood that vthe desiredfeffect on the inner 'surface v5 ofthe reflector lmayfbe producedin accordance with the construction of. theitubular member 6 shown and described lwithre'ference" to Figures 3, 5, 6, 7,9, 12, 15 and 16. In .l'iigur'e- 15 the tubular member 6 although shown as being of cylindricalformmay be of any of ltheforms shown in Figures 657,19, 12, 20 and 21. Insuch arrangement Vthe 'rear end `of theY tubular member 6is centredona'ringi41stampedup or spunin# wardly or provided as a separate fltment attachableto'the reflector 1. `Such-'an arrangement is more particularly intended for` use witha circular, oval, polygonal or vother `non'-rectai'igular .forni of tubularv member in cross section'. Wherehowever the tubular member is ofthe built up form such as shown in Figures 9, l0, l2'and 13- therear end of the built up member is centred on afring-42 having protecting :tongues143 a's-shown in' Figures 16, 17 and 18. The ring 43its onto aring'fsuch as 41 corresponding to the ring/41 inFigure 15 whichas previously stated may be .formed in one with the reflector 1iY or `may be provided as a's'epaf rateand attachable fltment thereto.` In the'con= struction shown inFigure` l-.the-tongues 43 are bent over on to the `strips (s'eeligure 18) forming the tubular member `6 so as toihold the said strips in position. 'Y If desired apolygonal frame similar to the frame 24 may be mounted roundthe strips at the front end thereof. It will be obvious from the foregoing description that the tubular member 6 or the parts thereof can be removed from the interior of the lamp when desired. In Figure 19 the tubular` member is replaced or substituted by a framework composed of a plurality of longitudinally arranged wires 44 or glass or transparent rods of Celluloid or the like soldered or otherwise secured to the reflector 1. The said skeleton framework may be tiedy at its outer end by a wire 45 or Wire clips such as 24 or other suitable means and also if desired at places intermediate of the wire 45 and the reflector 1. Transparent frosted, coloured or multi-coloured rings such as 46, 47 or strips 48 may be superimposed on the framework to give the desired effect on the reflecting surface 5 of the lamp reflector. In the circular form of tubular member 6 as shown in Figures 3, 5, 14, 15, 16, 18 and 23 and the oval form shown in Figure 6 as well as in the form shown in Figures 7 and 8 and the built up form shown in Figures 9, 10, 11 and 12, rings 49 of marled, mottled, frosted, satinized, self-coloured or multi-coloured appearance may be used either alone or in combination with strips 50 Figure 23 of coloured or uncoloured appearance.

In the advertising form of lamp shown in Figures 21 and 22 the tubular member may be of circular polygonal or other Adesired form in cross section or it may be of the form shown in Figures 1, 2, 3, 4, 9 and 10 or of the form shown in Figures 12 and 13 or other desired and suitable form. A suitable cross section however of the tubular member 6 for advertising purposes is the circular form shown in Figures 1, 2, 3 and 5 or the form shown in Figures 12 and 13.` In whatever form the outer surface of the tubular member as shown in Figure 23 may be provided with a plurality of ringssuch as 49 of transparent, coloured or frosted material which can be slipped on to the tubular member 6 and replaced by other forms of rings when desired. A more convenient form however is that in which the tubular member comprises an inner tubey 55 of clear coloured` or multi-coloured. plain. or mottledor f'marle'd glass orf-frosted orl satinized glass on which are preferably loosely superimposed a'pluralityof strips'56, 57, "58,559,430, 61, 62 and 63: Thesefstrips of glass oriother suit` able""transparentmaterial maybe self coloured aswell asbeing frosted,marled,.mottled, satin` izedv or they 'may v be onlyl self coloured; They must. however be transparent. so as to' permit of' the light l passingv therethrough and `the `tube 55 together-with -the said lstrips maybe 'rene dered `rigid'withthe lamp glass 2by Aadhesive or byv `helicalcircular springs ias Vshown in 'Figures 1 and 2 or by the construction'andzarrangement described with..reference to therin'gs 4l and. 42 in Figures 1'5, l6wand` 1'?.v One orA more Athan one strip is provided" withwadvertising matter suitablyfappliedll-thereto and ifA desired and in order toenhance the advertising eie'ct one or more than one disc 65er part disc maybe super-- posed aroundthe4 strips 57, 58;59 etc. thefsaid disc 65 being clear, transparent, frosted, coloured, multiecoloured," mottled, marled, satinized or treated in any otherdesired wa'y to enhance the nature of the advertisement'as reflected byprojection from the lamp reflector. Forli example the surface of `the saiddisc may be sand blasted or painted as bycoating or spraying with ma# terial` which is eitherftransparent or: adapted to give the` desired eifect1`^Again any advertising matter such as readable and/or pictorial matter may be applied to the said disc as well as to the strips by a transparent medium of any desired colour. The bulb and sleeve whether the latter be v,of an integral or built up nature may be removableand replaceable in the lamp casing as a single unit. The colouring of the tubular member panels, strips or rings either wholly or in part' may be obtained by wrapping a piece or pieces of transparent materialof the Adesired colour or coloursround the said tubular member, panels, strips or rings. M
